Improving the VR experience means improving the head tracking—and tracking means dots. Lots of dots.

Infrared dots, to be precise; they're generated by tiny LEDs embedded in the headset. You'll never see them during normal use, but our infrared camera sees all—just like the Oculus' tracker, known as "Constellation."

It's called Constellation because it looks like you're wearing a star chart on your face.

Turn your head around, and you're still being tracked. Unlike its predecessors, the latest Rift has IR LEDs in the front and the back. You can spin in circles and never break immersion—until you trip over the cord.
